A Cloud of Hope and Danger
A small cloud floats through the air in a hospital operating room. In the room a patient, suffering from cancer, lies on a table. The cloud surrounds(包圍) the patient, covering her body and filling her lungs(肺). The cloud is not smoke or steam. It is made of millions of microscopic robots called nanorobots(納米機(jī)器人). These tiny robots move from cell(細(xì)胞) to cell in the patient’s body, destroying the cancer.
Fighting cancer with nanorobots is only an idea today, but scientists say that it could be possible in the future. Using nanorobots for good purposes such as fighting disease or repairing the environment may be the solution to many of today’s problems.
However, nanorobots could be a dangerous risk as well. Since nanorobots are so tiny, they will have to work in large teams of many thousands to many millions. For this reason, nanorobots will have to be programmed to build themselves. Scientists will not have the ability to build millions of nanorobots one by one.
This ability to reproduce is making some scientists worried. What if something goes wrong in the programming? Quite a lot of crazy nanorobots would be far worse than any disease. Some people think that if they get out of control, nanorobots could destroy the Earth.
What should be done? Should we continue researching nanorobots or should we search for other methods? This is one of the many difficult decisions that we have to make in the future.

How to be a safe and smart SEARCHER
S
everal keywords will help to find better results. Use more than one keyword when you are doing a search. If you want to find out about seagulls, for example, search for and not just ‘seagull’ – because seagull might also be the name of just about anything else, from a hotel to a documentary film.
E
xact references can help you find what you’re looking for. If you are looking for an exact phrase or sentence, e.g. , type it between quotation marks (“”) and only exact matches will be shown. This is useful when you want to find something you’ve already seen but lost.
A
void common words like ‘a(chǎn)’ or ‘the’ in a search. These aren’t always helpful and are usually unnecessary.
R
emove unwanted results by adding a minus symbol (-). For example, would leave out all references to hotels and films.
91 . Make sure that you spell every word in the search box correctly. The smallest typing mistakes can bring unwanted results - especially when the mistyped word exists.
H
ave a filter(過濾程序). It’s a good idea to filter your searches, especially when you are searching for pictures. Ask an adult to help you add a filtering system. There are lots of filtering software options available.
E
xperiment with different search engines until you find the one that’s best for you. Some search engines personalise the results. So check out the option of using a search engine that doesn’t do this and you will get different results.
R
eliability is very important when you are searching on the Internet. Always ask yourself, “Is this reliable?” Don’t make the mistake of believing everything you see. Some websites are unreliable and some information is false. Check your information on other websites before accepting it.
1.This is an article written for adults, isn’t it?

After his Master Chef Junior run, 12-year-old Evan Robinson is using his kitchen skills to raise money for Puerto Rico(波多黎各). The TV show winner wanted to offer help after hurricanes(颶風(fēng))hit the country last September.
I’ve been seeing, all over the news, people lived too hard,”Evan said.“They can’t get fresh water, electricity. They can’t get really anything. I know I’m just a kid, but I think if a lot of people do something, a lot of things will get better.”
He raises money by baking and taking online orders for homemade pies. He started cooking on a recent Friday night. By the next Sunday evening, he had filled orders for 420 pies—roasted chicken, cheeseburger and vegetarian—getting $18 for six pies and $30 for a dozen.
For Evan’s out-of-town friends and supporters, he has also set up a crowdfunding(眾籌)page. Through it, he’s already raised $1,500 in“virtual(虛擬的)pies”. He said fruit pies are up next.
His mom, Veronica Robinson, is in charge of delivering the pies around the city.“We’ve never done anything like this before,”she said.“But it’s a great idea, so I want to help him.”
His baking will continue as well. This is because he heard on the news that it would take Puerto Rico years, maybe even 10 years, to recover(恢復(fù))from the hurricanes.
It’s not an easy job, especially for a kid with homework and Boy Scouts and friendships to tend to. But he doesn’t seem worried.“It’s what we’re supposed to do,”he said.“I’m a human. They’re humans. Why shouldn’t help them?”
1.Evan Robinsons was a TV show winner, wasn’t he?
